Vehicle cooling circuit

The invention relates to a vehicle cooling circuit for cooling a heat-generating device, in particular a battery, by means of a coolant guided in a coolant circuit, wherein the coolant circuit has a heat exchanger designed as an evaporator, via which the coolant circuit is coupled to a refrigerant circuit. According to the invention, the cooler is arranged downstream of the heat exchanger in the flow direction of the coolant in the coolant circuit. Furthermore, a bypass valve is arranged in the coolant line such that the coolant can be guided wholly or partially past the cooler.
